This invention relates to textile machines and more particularly to ayarn take-off and tension means for a doubling and twisting machine.

An object of the invention is to provide a simple, inexpensive andeasily adjusted'tension device and take-oi! for the over end delivery ofstrands of yarn to the twisting or other operating elements of a textilemachine.

Another object of the invention is to provide guiding means forindividual strands in a textile machine comprising loops formed at theopposite ends of awire, the central portion of the wire being bent orcoiled about a. supporting post or rod to resiliently and frictionallyretain the guiding means in position thereon.

And finally it is an object to provide a clamp engaging the'ends of thebent wire forming the guiding members to retain these ends at apredetermined angle to each other and also to tightly clamp the bent orcoiled portion of the wire about the supporting rod.

One feature which enables the above objects to be accomplished is thatthe tensioning means in the form of discs may rest upon the upper partof the clamping member for the wire forming the guiding means ordirectly upon the wire,

the discs being oppositely disposed so that the strand may pass betweenthem and partially about the supporting rod or preferably about a sleevesurrounding the rod, the tension applied to the strand being extremelylight and being adjustable by varying the weight of the upper disc.

with the above and other objects in view the invention includesthefeatures of construction and operation set forth in the followingspecification and illustrated in the accompanying drawing.

In the accompanying drawing annexed hereto and forming a part of thisspecification I have shown the invention embodied in a standard form ofspool support or creel for a doubling and twisting machine, but it willbe understood that the invention can be otherwise embodied and that thedrawing is not to be construed as defining or limiting the scope of theinvention, the claims appended to this specification being relied uponfor that purpose.

In the drawing:

Fig. 2 is a front elevation of the parts shown in Fig. 1. v

Fig. 3 is a plan view on a reduced scale of the strand guiding andtensioning means shown in Figs. 1 and 2:

Briefly, and in its-preferred aspect. the inven- 1 tion may include thefollowing principal parts: first, a substantially vertical rod or postdisposed in front of each vertical row of spools from which the strandsare to be delivered; second, coiledwirescloselycontactingthisrodorpostsothat they are fri'ctionallyretained in any position thereon, and there being as many coiled wiresas there are delivery spools; third, thread guiding loopsor eyelets atthe opposite extended free ends of each of the wires; fourth, discssupported on the individual wires so that a strand being delivered froma spool may pass between the discs and partially about the vertical rodas it passes from its spool and from one guiding loop or eyelet to theopposite loop or eyelet on the 5 opposite ends of a wire; fifth, aclamping member engaging over the opposite end portions of i the coiledwires to hold these end portions at the proper or any predeterminedangle to each other and to firmly tighten the coiled portion of thewires frictionally against the vertical rod or post; and sixth. afelt orother member on the upper surface of the clamping member upon which thelower disc rests.

Referring more in detail to they figures-of the drawingthere is provideda delivery spool support in the form of a frame it having spaced pins Iioutstanding therefrom upon which the spools ii are mounted. In thedrawing but one vertical row of spools i2 is indicated but it will beunderstood that there will be a plurality of similarly supportedvertical row of spools in any machine to which the invention may beapplied.

Directly in front of each row of spools I2 is a supporting bar or rodII. The lower end of this bar or rod It may be attached as shown inFigs. 1 and 2 to the support Ill and the upper end similar or in' anyother preferred manner attachedto the support-ll or to an intermediatemember (not shown). n the rod l2 and disposed substantially in iront oieach spool I2 is a take-oi! and tensioning means presently eyelet II.The loop I4 is disposed in a position to guide a strand from a spool l2to tension discs I1 and It on the bar I! and the eyelet ll guides thestrand after passing between the discs l1 and II and as it passes to adrop wire l9.

The discs l1 and I! referred to above are rod, spaced wires having aconnecting portion dished as shown most clearlyin Fig. 4 and areoppositely disposed. Their central opening is large enough to permitthem to pass over the rod l2 and over a sleeve of wear resistingmaterial, also slidable over rod l3. To place a slight drag on the discsI! and I8 so that a slight but appreciable tension will be placed on thestrands the lower disc I! rests on a pad 2| of felt or other fibrousmaterial. This pad 2! may be of ring iormand fit within the concavedportion of disc ll. The pad 2i may rest directly upon the upper end ofthe coiled portion of wire it but preferably and as shown in the drawingrests upon a clamp member 22 and holds the disc-i1 slightlyspaced-therefrom.

Clamp member 22 tits slidably over the rod l3 and forms a small platformfor the pad 2|. This portion of the clamping member is plane and isdisposed substantially horizontally and maintains the discs I! and It intheir proper relative positions to their sleeve 20. From this centralportion of the member 22 extend two downwardly extending clamping arms22 and 24. Arm 2! clamps around the end of wire it upon which eyelet I5is secured and arm 24 extends around or clamps the arm provided with theloop i4. As the arms 22 and 24 are integral with the central portion ofthe clamping member 22 the angle between the arms of wire l6 carryingtheguiding members l4 and I5 can becontrolled so that the guiding loop I4and the eyelet I! can be positioned at any proper relative angles toeach other for the particular disposition and guiding of the strandscalled for by the machine on which they are mounted.

In addition to positioning the guide carrying arms of wire it at theirproper angles the clamp 22 serves to bind the coils of the wire i6 moretightly against the rod II to firmly hold the complete assemblyirictionally thereon. To change the position of the assembly up or downon the rod it it is only necessary to release the clamp arms 23 and 24of member 22 from the ends of wire I6, separate these ends slightlymanually to slightly enlarge the opening within the coiled portion, andthen slide the coil I6 to the desired vertical position. After the clamp22 .is replaced in position the coil I will again firmly and resilientlyengage the rod I2.
